Distribute
4x+3x-6=-20
7x-6=-20
add 6 to both sides
7x=-14
divide both sides by 7
x=-2
For what shape? It depends on the shape
This is a simple problem with some quick addition and subtraction, and a bit of multiplication.
First we figure out how much money you're spending in total, which is $300 each year, for 20 years, so 300 x 20 = 6,000. Now, since the problem is asking for a maximum amount for percentage rate, this means we find the 9% for all 20 years combined and not individually. 9% of 6,000 is of course 540, so if we subtract 540 from 6,000, we get 5,460.
This means your answer is $5,460
Answer:
<h2>Solution: each real number</h2>
Step-by-step explanation:
"Inverse of an exponent?" Unsure of what you mean. Do you want to find the inverse of an exponential function?
Suppose y = 2e^x. Find the inverse function:
1. Interchange x and y: x = 2e^y
2. Solve this for y: ln x = ln 2 + y, so y = ln x - ln 2, or y = ln (x/2) (answer)
